If you create a "metaethnicity" of all Germanic language speakers in continental Europe (German s, Dutch, Swiss, Austrians, Flemish, Alsatians, German-Russians), there are about 50 million Americans of a Germanic metaethnicity in the U.S., about 21% of the population.
Wow, that's very interesting. That stat really separates Canada from the US. I wonder if the ratio was that high in the years leading up to the American Revolution? The melting pot was obviously a success as all Americans banded together to fight the Germans, despite the fact so many have a Germanic lineage.
